Why articles a or an the are not used before word India?

You are correct! We don't use "a" or "an" before "India" because it is a proper noun.

Here's why:

* Proper nouns are names of specific people, places, or things. They are always capitalized.

* Articles (a, an, the) are used to indicate whether a noun is singular or plural, and whether it is definite or indefinite.

Since "India" is a specific country, it's a proper noun and doesn't need an article.

Examples:

* Correct: I went to India last year.

* Incorrect: I went to an India last year.
